Hi @sunjeet-khokhar Creating and closing browser instances is done automatically at the start and end of tests. However, if your tests open up a new browser window using driver2 = self.get_new_driver(), you can close that second driver using driver2.quit(). Especially useful if your tests open up a lot of new browser windows. You should not be closing your main browser window on your own, as that will break features such as --reuse-session / --rs, which makes test suites run faster by reusing the same initial browser window for all tests. If using the reuse-session feature for tests that log in to sites and save login cookies, you may also want to add in the --crumbs argument so that browser cookies are cleared out between tests that reuse a browser session.
